Application filed Becember 13, 1916. Serial No. 13G/71s.

To ill whom may concern.' 'Be it known that I, STEVE Kutten, subdoors to garages and similar structures.

@ne of the main objects oi the invention is to provide` dooropening means of simple construction and operation which act normal'ly to maintain the door in closed position and maybe quickly and easily moved into inoperative position so as to release the door. A further object is to provide simple andetc'ient means for moving the securing means into v inoperative position, such means being adapted to be actuated by the wheels of an automobile or similar vehicle. A

further object isto provide :means for releasing the securing means manually. Further objects will appear from the detail description. 1.

ln the drawings: Figure 1 is a front view of agarage with means constructed in Vaccordance with t e invention applied,

Fig. 2 is 'a top plan view of the same, Fig. -3 is a central longitudinal vertical sectional view taken through the garage and door securing means,

Fig. 4 is a transverse vertical sectional view taken through the `garage inside of the doors,

Fig. 5 isa section through one of the sup- 'porting blocks taken substantially on line 5-5 of Fig. 3,

Fig. 6 is a detail sectional view taken sub- Fig. 7 isa fragmentary sectional view of one of the securing bars and heads.

The garage 1 is provided with doorway 2 above which is supported a track 3.

-they completely cover the door opening 2,

inthe usual manner. VEach door 4 is provided, 'at its upper inner corner, with a vertically extending linger 6. A. cable 7 hasl one end secured to 'this lnger and is passed lockingrod 1 over a pulley 8 mounted at the side of the garage, a weight 9 being ,secured on the other end of the cable. These two weights act-.normally to move the doors 4 apart so as to uncover the door-way or opening 2.

A rectangular bar 10 is slidably mounted on the inner face of each door 4, near the inner edge thereof, in two securing straps 11. Each of these rods is provided, at its lower end, with an integral head 12, and is normally held in depressed position .by an expansion spring 13 which is coniined loe-l tween the upper strap 11 and a collar 14 secured about the rod above the lower strap. The head 11a of each bar is provided, on its inner face; 4with alternately arranged teeth and recesses, the teeth of one head meshing with those of the other, as at 15 so as to prevent independent vertical movement of the bars..

Head 12 is provided with an axial bore adapted to receive a securing pin 16 formed integral with a locking rod 17. Rod 17 `is auA 23 is bifurcated to receive the stem 17I1 of the locking rod, which is pivotally secured therein by a pin 26. The lower portion ofV plunger 23'` extends into the slot 21, whichV` is of sufficient width to accommodate the plunger, and an expansion coi'l spring 27 is mounted about the plunger .and confined between the head 24 and the annular shoulder at the lower end of the cylindrical bore` 22. This spring acts to normally main' tain the plunger 23, and consequently the 7, in raised position. v With the rods 17 in this position, the bars 10 are each secured against lateral .movement by means of the fingers 16,.thus edectually pren venting opening of the doors 4.

.ln practice, two locking rods are employed and are mounted in 'parallel spaced relation in a housing 28. The heads 24 are so spaced as to'be engaged by the Jfront wheels of an automobileapproachingthe garage.

.The weight of the automobile retransmitted imv the heads so as to depress the plungers 23. IiVlien the plungers are depressed,'the locki ing rods 17 are rocked downward about their ivotal axes so as ltb release'the bars 10.

ven the bars 10 .are released the Weights.

9 act to move the doorsto'war the sidesof the garage seas to open the same, thus ren,

dering it possible to open lthe garage for.

entry ofan automobile without the necessity of the driver getting out'of the machine.

In order that the doors may be .opened when the automobile is within the garage,l

I- provide supplemental means for releasing the locking bars 10 fromA the pins 16.v For this purpose a' rod 29 is rotatably mounted through one of the doors 4, a suitable knob 30 being provided at 'each end of this rod. A pinion 31 is secured on rod 29 and meshes with a rack 32 formed integral with one of the locking bars 10. By rotating the'rod 29 the two bars 10 may be raised against the action of the expansion springs 13, so as to disengage the heads 12 from the locking pinsl. As soon as the bars have been raised into this position, the weights 9 will act to open the doors in the manner previously described. p i

While I have described my invention speciiically as 'applied to garage, doors, it will be evident that it can be used for many other purposes such as doors and gates of various types. It will be evident that there may be slight changes made in the construction and arrangement .of the-ditferent parts of my invention Without departing froml the field and scope of the same, and I intend to include all such variations, as fall withinl the seopeof the appended claims, in this'application in which the preferred form only ot my invention is disclosed.

What I claim is 1. In door securing means, the combination of two oppositely movable doors, a lock# ing bar carried by each door, a ioclably 'mounted securing' rod normally engaging said locking bar so as to prevent lateral movement of the door, and means for moving said securing rod into inoperative position.

for depressing said rod so as to release the' locking bar. A

3. In door securing means,wthe combination of two oppositely movable doors, a locking bar slidablymouiited on each door for 2. In door securing means, the combina-` in presence of two vertical movement, maiisfor -normally holding saidbar in depressed position, a se lcuring rod positioned beneath thc locking ,65

bar and iioiiiially iii engagement therewith s o as to prevent lateral movement of the door, said securing rod being mounted for rotary movement about'a horizontal axis, a plunger 'pivotally secured to". the securing 70 between the inner end and the pivotal axis thereof, means for normally holding the plunger in raised positiom'and manually operative ineans'tor raising the locking bars.

- 4. In door securing means, the, combii'ia- 75 tion of two oppositcly movable doors, a locking bar slidably niolitfitcd on eachv door for, vertical movement ajntlA provided Iwith an axially extending bore in its lower end,.

means for'noi'iiially holding the bar in de- 8ok pressed position, a securing rod having a. pinI adapted to engage into the bore of said lockiiigbar and pivotally mounted on a horizontal axis at its outer end, a plunger pivotally secured at its lower end to the said securing bar and providedwith an extended head at its upper end, an expansion spring mounted about the plunger and acting t0 iiormall hold the same in raised position,

means or raising said lockiig bars so as to diseiigage the saine from said locking pins, and means for moving tliedoors into o open position when the locking kbars are released.

5. In a door securing means the combination of two oppositely movable doors, paralllel locking bars ymounted niovably on said doors, means for normally holding said. bars in depressed position, a securing-rod positioned beneath each locking bar and nor- 'inally in engagement therewith so as to prevent Vlate/ral movement of the door, and means for operating said securiii rodfto release said locking bar and permit. lateral ,i movement of said door. 105

6. In a door securing means the com-bination of two oppositely movable doors, alock'- ing bar mounted movablyon each door, meansA for normallylioldng said bar in depressed position, a pivot memberrengaged with said locking ybar tio prevent lateral movement of the door, said means -being f .pivotally mountedflmeans for normally retaining said pivot member in engagement with said lockiiigbar, and means for movv ing said pivot means upon its pivot to rer, lease said lockingfbar and permit lateral movement of the door. l In testimony whereof I atiix my signature Witnessesi l STEVE KULIcH.
